PAGE, F BINGHAMTON, NEW ASSIGNOR T0 THETABULATING MA- CHINE COMPANY, OF ENDICOTT, NEW YORK, .A CORPORATION 0FNEW JERSEY QUICK Parma INSEMING DEVICE Application led September 16,1926. Serial No. 135,792.

This invention relates to accounting machines and more particularly to apaper inserting device to be used in conjunction therewith.

In machines of the above type considerable time is wastedV inpositioning the paper with regards to the margin desired at the top,whereas in my device this operation is done simultaneously with thepaper inserting operation.

An object of my invention is to improve generally an apparatus of thiskind.

Another object is to provide economic and efficient means for insertingpaper under the platen roll.

Another object is to provide convenient means so that substantially anypart of the paper may be brought into relation with the platen roll.

A further object is to eliminate the adjusting of the paper after it hasbeen inserted under the platen roll.

A still further object is to provide a storage roll whereby the dataprinted on a sheet of paper may belwound simultaneously with theprinting operation.

Other ob'ects and advantages of my invention wil be set forth in thefollowing description and drawings in which:V 80 Fig. 1 is a sideelevation of my device according to the invention;

Fig. 2 is a detail view of the paper feeding mechanism shown in Fig. 1;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a. sectional View showing the coil spring and governor forreturning the rack to normal position;

Fig. 5 is a. sectional view taken on line 5 5 of Fig.l 1.

Referring more particularly to the drawings, Fig. 1 comprises a frame 1attached to an accounting machine or the like in the usual manner sothat the platen roll will be in position to cooperate with the type.

Mounted in said frame is av platen roll 2, Fig. 3, revolved by means ofshaft 3 rotat ably supported on frame 1. A dispensing roll 4 is providedfor feeding paper-5 onto platen roll 2. Rigidly aiiixed to dispensingroll 4 at each end is a shaft 6 which revolves in frame 1. Attheuppermost end of frame 1 is another roll 7 acting as a storage orreceiving roll. Storage roll 7 'is revolved by means of shaft 8 andsupporting center 8a. A shaft 15 is provided at the left side and hasslidably mounted thereon a supporting vcenter 16 which is actuated byspring 17 into engagement with roll 7. By pressing supportlng center 16against coil spring 17 said storage roll 7 may be easily removed. Shaft8 revolves in frame l and boss 9 and has mounted thereon at 10 afriction driving ring (see Figs. 1 and 3) which friction driving ringhas aiixed thereto a pulley 11. Friction driving ring 10 is comprised oftwo portions 10a and 10b hinged at 10c closed upon shaft 8 byymeans ofspring 19. Frio tion driving ring 10 and pulley gear `11 are freelymounted on shaft 8. By means of a n nut or washer 12 fastened to the endof shaft 8, pulley 11 is held in position. Fixed onto shaft 3 at 13 isanother pulley which upon rotation of platen roll 2 causes .pulle 11 tobe rotated through the medium of a lt 14. Pulley 13 is larger thanpulley 11`in order that the roll 7 shall turn more rapidly than theplaten and thus hold the paper tightly Wound thereon. As the paper 5accumulates on the storage roll 7 it is obvious that as the roll becomeslarger rotation of same will become slower although belt drive 14continues to run at the same speed. Friction driving ring 10 will slipupon shaft 8 thereby causing roll 7 to revolve at a much slower speedthan that of driving belt 14.

Referring to Figs. 1 and, 2, ri 'dly affixed to disc 21 is a spur gear2O both eing freely supported upon shaft 3. Gear 20 meshes with theteeth 44 of rack 27. Pivoted to disc 21 at 22 is an actuating pawl 23biased by spring 24 to cause engagement of said pawl with ratchet wheel25. Ratchet wheel 25 is rigidly affixed to star gear 26 which staf!`gear is firmly mounted o'n shaft 3. When rack 27 is pulled to forwardposition, pawl 23 actuated by spring 24 cooperates with-ratchet Wheel 25and causes rotation of platen roll 2. Rack 27 has fixed thereonextending horizontally on the inside of samea channel b ar which holdssaid rack in place by means of roller bearings 28 which bearings arecarried by frame 1 by means of brackets 29. Extending along the top andbottom of rack 27 are teeth 44 meshing with spur gear 20 and pinion gear30. A groove 31 is provided on the front of rack 27 to cooperate withstop 32. Stop 32 (see Fig. 5) is slidably mounted on rack 27 by means ofianges 33 reaching over the back of the rack. A tooth plate 32a fixed tothe stop 32 meshes with the rack teeth 44 to prevent the stop fromcreeping. B

lifting and sliding stop 32 it may be moved along the teeth on the rackto any desired position.' Afterthe determined position is reached toothplate 32a on stop 32 meshes with .the teeth 44 on the upper part of rack27 and same is rigidly held in position by turning of set screw 34 whichset screw has a wedge shape projection 35 gripping itself firmly intogroove 31 on rack 27. Wedge shape projection 36 on stop 32 upon pullingof rack 27 to forward position engages itself in star gear 26 (see alsoFig. 2) thereby allowing the paper inserted on the platen roll to berotated an equivalent distance to which the stop 32 had been previouslyset. A handle 37 (Fig. 4) is rigidly affixed to rack 27 at 38 andprovides for the pulling of said rack to forward position. As shown at37a on the rack 27 numerals and graduations may be provided to enablethe operator to deter'- mine where to set` stop 32. When rack 27 ispulled to the forward position pinion 30 mounted on shaft 39 causes atension to be made upon coil spring indicated by dotted lines 42a indrum 42 (see Fig. 3). The coil spring automatically returns rack 27 whenreleased to its normal position. The spring box or drum 42 is mounted onframe 1 by means of a plate 41a and screws 41. A governor indicated bydotted lines 426 may also be provided in drum 42 to prevent shock whensaid rack 27 is returned to its normal position. The construction andarrangement of the spring and governor are not shown in detail as anyconventional construction may be employed. After rack 27 has beenreturned to its normal position a pin 43 firmly lfixed on rack 27engages with the tail 23a of pawl 23 drawing same out of engagement withthe ratchet 25 thereby allowing the carriage to be turned manually ineither direction.

6. In a printing mechanism, a platen roll for carrying and feeding asheet, and means for line spacing the sheet comprisingv a notched Wheelxed relative to the platen roll, means for rotating the roll, and atooth adjustably carried by said means and ada ted to mesh with one ofthe notches in the W eel to stop the feeding of the sheet and aline itin proper spaced position.
